Pocket-lint has a rumour up that Facebook is interested in acquiring Opera to kickstart their own move into the browser market, to compete with Mozilla, Google, and Microsoft. While it would mean much-deserved recognition for Opera, I actually hope such a deal does not go through - for entirely selfish reasons.

A while ago, the facebook app was quite different from the site. Nowadays, the site and the app are exactly the same. So, I really wonder if it is just a "site-dedicated-browser" indeed.

As for facebook-opera. I hope Opera will remain independent. No facebook browser please. Besides all of that, from my experience, it always felt to me opera was less-supported by facebook then gecko or webkit based browsers.
